The mohawk (also referred to as a mohican) is a hairstyle in which, in the most common variety, both sides of the head are shaven, leaving a strip of noticeably longer hair in the center. Mohawk hairstyles have existed for thousands of years. As of the 21st century, they are most commonly associated with non-conformity.

The mohawk is also sometimes referred to as an iro in reference to the Iroquois (who include the Mohawk people), from whom the hairstyle is supposedly derived – though historically the hair was plucked out rather than shaved. Additionally, hairstyles bearing these names more closely resemble those worn by the Pawnee, rather than the Mohawk, Mohicans, Mohegan, or other groups whose names are phonetically similar.

The world record for the tallest full mohawk goes to Joseph Grisamore, also know as the Mohawk King, who has a 108-centimetre (3 ft 6+1⁄2 in) tall mohawk, while the world record for the tallest mohican hairstyle goes to Kazuhiro Watanabe, who has a 113.5-centimetre (3 ft 8+1⁄2 in) tall mohawk.
